SPI T6963C Graphic Lcd Library

The mikroBasic PRO for FT90x provides a library for working with Glcds based on TOSHIBA T6963C controller via SPI interface. The Toshiba T6963C is a very popular Lcd controller for the use in small graphics modules. It is capable of controlling displays with a resolution up to 240x128. Because of its low power and small outline it is most suitable for mobile applications such as PDAs, MP3 players or mobile measurement equipment. Although this controller is small, it has a capability of displaying and merging text and graphics and it manages all interfacing signals to the displays Row and Column drivers.

For creating a custom set of Glcd images use Glcd Bitmap Editor Tool.

Important :

When using this library with FT90x family MCUs be aware of their voltage incompatibility with certain number of T6963C based Glcd modules. So, additional external power supply for these modules may be required.
Glcd size based initialization routines can be found in setup library files located in the Uses folder.
The user must make sure that used MCU has appropriate ports and pins. If this is not the case the user should adjust initialization routines.
The library uses the SPI module for communication. The user must initialize the appropriate SPI module before using the SPI T6963C Glcd Library.
For MCUs with multiple SPI modules it is possible to initialize both of them and then switch by using the SPIM_Set_Active() routine. See the SPI Library functions.
This Library is designed to work with mikroElektronika's Serial Glcd 240x128 and 240x64 Adapter Boards pinout, see schematic at the bottom of this page for details.
To use constants located in __Lib_SPIT6963C_Const.mbas file, user must include it the source file : include __Lib_SPIT6963C_Const.

Some mikroElektronika's adapter boards have pinout different from T6369C datasheets. Appropriate relations between these labels are given in the table below:
